Q147 / 150 · MHT CET 2023 (11 May Shift 1) · Physics

An electron is projected along the axis of circular conductor carrying current I. Electron will experience

  • Correct answer
    A
    no force.
  • B
    a force along the axis.
  • C
    a force at angle $30^{\circ}$ with the axis.
  • D
    a force perpendicular to axis.

Solution

The magnetic force experienced by the electron, $\mathrm{F}=\mathrm{qvB} \sin \theta$ As electron is projected along the axis, $\theta=0$ $\therefore \quad \mathrm{F}=0$

Hence, the correct answer is option: 'A'.
